DISK HARROW;

Specification of Letters Patent. P t t y ggg,19

Original application filed June20, 1914, Serial No. 846,225. ..Divided and this application filed February I i ,12, 1915. Serial No.,7,701.

To all whom it may concern:

Be it known that I, FrnDnnIoIcC. annin, a citizen of the-United States,residing at Mansfield, in the county-of Richland and State of Ohio, have invented certain new and useful Improvements'in Disk Harrows, of which the following is a specification.

My invention relates to improvementsin disk harrows of the pivoted gang type, the invention of the present application relating to an improved draft frame and means for connecting such draft frame with the gang frames and disk gangs, together with an improved foot controlled disk gang regulating or leveling device for use in such connection such as shown and described my application filed June 20, 1914-, Serial No. 846,225, and of which this application is a divisional part.

The primary object of the inventionis to provide a generally improved draft frame and means forconnecting such draft frame with the gang frames and disk gangs where by the latter; are free to be adjusted at any desired angle of incidence relative to the line of draft and are also adapted to be moved laterally toward or from such line of draft through the medium of suitable pivotal connections with the draft frame, one object being to make such connections substantially rigid as against any tendency of the draft frame to rise or fall relative to the gang frames.v

Another object is to provide an improved foot controlled disk gang regulating and leveling device for use in connection with such draft frame whereby the draft bars and the inner ends of the disk gangs may be simultaneously adjusted or depressed in any of the various adjusted positions of the disk gangs to the line of draft, this function being performed through the medium of the leveling or snubbing block interposed between the draft bars and the draft frame and provided with an improved upwardly extending foot lever and mechanism for securing the latter in any desired adjusted position.

.With the above mentioned and other ends in view,- the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in one of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

, Referring to the drawings, forming a part relation to each other in operative use in cultivating the soil. Fig. 2, an isometric view of the draft frame and its connections, looking downwardly from in front of and at one side thereof and illustrating more particularly the improved foot controlled d sk gang regulating and leveling device. F 1g. 3, a detached view, partly in side elevation and partly in central longitudinal section through the draft frame, and illustratlng more particularly the disk gang leveling device and the connections between the latter. and the stub pole and adjustable draft bars leading to the inner ends of the disk gangs. Fig. l, a fragmentary side elevation of the draft and brace bar connections at one side of the improved draft frame. Fig. 5, a fragmentary rear view of the same. Fig. (3, a fragmentary top plan view of the same.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

The improved disk harrow comprises a draft frame consisting, in the present instance, of a transverse bar 1, and a curved draft framemember 2, the latter having its forward middle portion secured to a stub "pole 3, which latter is made up of spaced angle bars secured at their rear to the transverse bar or member 1, said stub pole being adapted to receive a fore-truck i, as shown, or other suitable draft appliance. The stub pole 3, is provided with a set of pivotally mounted vertically extending levers 5, and

suitable cooperating sector racks 6, the lower,

ends of said levers being connected to draft bars 8, the latter having their rear ends flexibly or pivotallyattached to bearingor axle boxes 9, at the inner ends of the front disk gangs whereby the latter may be given the desired angle with respect to each other as well as relative to the line of draft.

As a' means of connecting the draft frame to the disk gangs, draft bars 10, are pivotally connected to the under outer portions of the curved framemember 8, (see Fig. 4;) and in front ofthe transverse bar 1,-said draft bars extending rearwardly beneath the latter and being flexiblyflconnectedto axle boxes 9, at or near the centers of the disk gangs, and as a means of limiting the lateral movements of the draft bars 8,]the under siderpo rtions of the transverse bar 1, are provided with cut-away portions 1*, providing stop shoulders 1, as shown most clearly in Figs. 4 and 5 of the drawings. As a means of supporting and maintaining the draft bars 10, in proper relative position to the transverse bar 1, the latter are provided withsupporting clips 11, adapted to be moved horizontally and laterally as indicated by dotted lines in Fig. 6, said clips being pivotally connected to the top portion of the draft bars 10, and at the rear of the transverse bar 1, and as a means of flexibly connecting the draft frame to the" upper or transverse bars 12, of the diskgang frames,

I brace members13, are provided, the latter extending upwardly and rearwardly from the top of the transverse bar 1, of the draft frame and being likewise pivotally connected to the bar 1, with the supporting clips or braces 11, by pivotsecuring bolts 14. Brace members 13 also extend from the inner ends of the bars 12, of' the disk frames to the adjustable draft bars 8, connected'to the lever members 5. The disk frame bars 12, are connected to the axle boxes 9, by means of supporting bracket or brace members 15. I

The improved scraper blade supporting actuating and adjusting mechanism for the -disks comprised in the disk gangs being the draft frame, said leveling or snubbing block 16, in the present instance, being disposed immediately beneath the transverse bar 1, and pivotally attached to the latter by means of bearing brackets 17 said block 16, extending forwardly and, in the present instance, being provided with depending lugs 16*, adapted to frictionally receive and retain the longitudinally movable draft bars 8, as well as form a friction bearing member for the latter in any of their various adfjusted positions in angling the disk gangs to the line of draft.

As a means of depressing *theforward" ends of the leveling or, snubbing block 16, r

and consequently depressingthe; draft bars 8, and the inner endsof the disk Qgang's,'tlie forward or free ends 'of fftheTpivotally mounted block 16,'is-provided' with an upwardly extending foot lever or rack arm. 18, whereby the operator or attendant from the seat of the harrow may bythe foot, positively depress the foot lever and-mensequently depress the draft bars through the medium of the lever or tilting. movement imparted to the pivoted blockf lfi, and as a means for laterally locking the foot'lever in any desired depressed-position, a rack engaging lever or dog 19, is pivotally'mounted beneath one of the members of the stub pole 3, and'extends outwardly and rearwardly at one side of the latter, terminating in; an upwardly extending bracket portion 19, for the convenient operation ofthe lever or'dog in releasing by the foot thetoothed portion; of the foot lever when desired, and as a means for holding or drawing the free portion of the lever or dog 19, toward the rack arm or lever 18, a spring 20, maybe a mounted beneath the stub pole 3, and secured to the latter by means of a bolt 20, as shownmost clearly in Fig. 3 of the drawings. i From the foregoing description, taken in connection with the accompanying drawings, the operation and advantages of my invention will be readily understood.
